A positive charge is attracted towards a negatively charged ion and the force with which they are attracted towards each other is electrostatic force of attraction.
According to coulomb's law, force is directly proportional to the product of charges and inversely proportional to the square of distance between them.
Mathematically, F
Therefore, smaller is the size of ions greater will be its charge and more strong the ions will be held together.
Thus, we can conclude that the compound that has the smallest ions with the greatest charge would be expected to have the strongest ionic bonds.
With every electron stationed in its own orbital or paired off with each other in the higher energy level, the energy level is balanced and stable. The atoms that utilize this exception are Molybdenum, Chromium, Gold, Silver, and Copper.
